In order to ellcct auton'latic vertical adjustinent o1" tholecd tablc 69during feed of the paper, automatic means are provided aojacent theretoactuated by a. crank and pitnian 11"?) from an and disk 10? of thesuction cylinder 82, as seen in Fig. 1., the details of which automaticmeans are included in a separate application lilcd August 5, 1915, andserially numbered 43783. Around a pulley 108 connected to shaft 51) by aclutch 11 is extended the rear end of a belt 114, the forward end ofwhich belt, as plainly seen in Fig. 1. is extended around one endportion of the suction cylinder so that whcn the pulley 108 is clutchedthe rotation of the suction cylindcr communicated to the shaft 59,rotating the same to Similarly rotatc tlin crcw liars fill and lowerthe. table 19 when its paper stack has become c.\' haustcd.

From Fig. and also from Fig. 2, it will be noted that onc of thebearings 61% of the adjacent side brackct provided with an extendedhearing or tubular piece loosely through which extends a vertical rod116 haying an adjustable sot collar 117 se curcd thcrcon below the saidsidc bracket, and with which tlic extended portion 115 just mentionedcomcs into engagement when inc table is lowered through the action ofthe elt 114, thus causing lowering movein ot of the rod 115. thc ilppcrend of which is secured to a llcxible coniicbtion 118 passing own apulley 119 support-ml upon the ad iar-cut upper side framc andc-imnected at its torward end to a clutch operating 1neniher fordisengaging a clutch in the driving connections to the suction cylinderR2. as hcrcinaltcr (inscri ed, when the table 69 has thus been lowci .L.

Rcfcrring again to Fig. 1. it will bc noted that tho reduced end portionof the ;'-:uction cylinder 82 is provided with a pair oi gr 1113 and 169in respective connection with suimratc gears 170 and 171 of the shaft172 of a wooden roller 1137. The shunts of paper delivered by the actionof the continuously rotating suction cylinder 82 upon tapes 166. therear ends of which pass around the wooden roller 167, and the l'orwuirdends of which pass around a roller 175-. usscen in Fig. 1, and carriedforwardly by said tapes in their movement between sidc paper guides and181 parallel with the side lrainc bars 182 and 183, are deliveredbetween su. perposed rollers 184 at the rear of the ruling plainly seenin Fig. 7.

Thegear 187 is also provided with a sprocket wheel 189 and from thissprocket wheel a sprocket chain 190 extends longitudinally along andoutside of the frame side bar 183 as will be clearly seen by referenceto Fig. 1. with its rear end around a sprocket wheel 191 looselydisposed upon one projecting and of the shaft .172 of the woodcn roller16? before mentioned. This sprocket wheel 191 is connected to the shaft172 of the wooden roller 16? by means of an automatic clutch to be nowdescribed, as particularly shown in Figs. 5 to 8 inclusive.

Referring now to Fig. 5 it will be seen that the sprocket wheel 191. isrigidly attached by machine bolts 192 to the outer side of an annulardisk 193 also loose upon the shaft 172. this disk carrying a pair ofspring controlled pawls 19lnormally in engage ment with tho tenth of aratchet wheel 195 secured upon the shaft 172 as clearly seen in Fig. l3.pawls 191 having laterally and inwardly projectingpins 1% adapted f rengagement by the annular beveled face 197 of a clutch, controllingmember 198 longh tudinally sliiflablc with respect to the shaft 172 andhaving at its inner end a cam shoulder 199 normally disposed within acon tornr able recess 200 at the outer and of a slccve 201 disposed onthe shaft 172 and hcld against rotation by means of pins 202 rigidtherewith and cntcring rcccsscs in the adjacent bearings 171 of thoshaft 17:2 as plainly seen in Fig. 5. the relatively engaging camshoulder 1 9 and recess 200 being Thus rot-alive movement of the clutchcontrolling member 198 in citlicr direction scrves to shift the samelongitudinally of thc shaft 172 toward the ratchct wheel 195, the resultbeing that its conical face 19? engages the pin 196 of the pawls 194 soas to shift the pawls on thcir pivots away fron'i, and out ofcngagcnicnt with. the ratchet whecl 15): before 1nc11- tioncil.

To this and the lutch controlling 111emher has an upright rigid arn1203to which the for ard end of the flexible conneclion 113 is secured, therear end of which connection is secured to the YOlllttlllV shiftablc rod116 as hci'orc described. To the ui'iright arm 203 is also end of aconnecting rod 201 extending forwardly along the machine and connectedat its forward end to a cam disk 205, as Will be plainly seen byreference to Figs. 1, 2,

connected the rear and 3. Referring now particularly to Fig. 3, it willbe noted that the connection of the forward end of the actuating rod 204is above the fulcrum 206 of the cam disk 205 upon the outer face of theframe side bar ings 214 attached to the side frame bars 183 as best seenby reference to-Figs. 1, 2, and 3, and is provided with forwardly andrearwardly projecting arms 215 and 216 respectively, the latter armbeing loosely connected to the shaft 213 to swing freely in a verticaldirection thereon, and having at its rear bifurcated end a roller 217bearing upon the wooden roller 167 as shown in Fig. 1 and mentioned andCont iiling the cam plate 205. When, luiwever, two sheets are fed at thesame time upon the tapes 166, the in creased thirknesspf the material sofed causes upward movement of the arm 215,

Thus from the foregoing description of The forwardlyprojecting arni 215 is the construction and operation of the sevi'igidlyconnected at its rear end to the said end parts of this machine, it isbelieved shaft 213, and is provided at its forward end with a roller 218as plainly seen in Figs. 1 111(1 3, which roller bears downwardly uponcompanion roller 21!) mounted upon a ower transverse shaft 220 (see Fig.1), ex the passage of two or more sheets beneath ending between the sideframe bars 182 the roller 218, the operator may release ml 183, belowthe upper run of the tape these parts by the operation of a handle 27466, this latter shaft being provided at carried by the end of the shaft213 opposite no side with a sproqhet whccl 221 con to that to which thearm 212 is connected, as cctcd by a sprocket chain 222 (see Fig. 3 bustseen in Fig. 1.

It is to be noted, however, that in additionto the automatic release of the clutch shown in Figs. 5 to 8 inclusiveby the clutch is withdrawn by rearward oscillating movement of theclutch operating 'mcmbcr 198, thus disrupting the driving connections.'hcn ahew supply of paper sheets has bccn furnished, the table is thenelevated to the proper position as best seen by reference to Fig. 2, bythe hand crank (33. It will be understood that a machine so constructedwill be light in weight, practical and efficient in its operation, andstrong and durable in use, and that the feed ing parts may be controlledthrough the adjustment of the driving connections best shown in Fig. 2from the ruling machine, so as to accurately and minutely adjust andtime the feeding operation in accordance with the movement of theoperating parts of the ruling machine itself, sheets being fed either atdesirably spaced intervals, or in a practically continuous I mannerwithout danger of two or more sheets arriving at the ruling machine atthesame time, and with the attention of but a single operator.

It is further to be understood that while I have shown and described myimprovements particularly in connection with a ruling machine, they maybe adapted with equal facility in connection with printing machines,embossing machines, paper box making machines, sizing apparatus, and infact any machinery to which it is desired to feed Sheets of paper insubstantially the manner set forth, and each of the foregoing referencesto a ruling machine is therefore to be taken as merely representative ofthe class of machinery to which my invention is adapted for application.
